Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, and in particular to a battery pack transfer and hoisting tool. Background Technology

[0002] The heavy-duty truck battery pack enclosure is installed within a multi-layer truck-specific bracket. Mounting holes are pre-drilled at the bottom of the battery pack, which is then lifted by threading straps through the bottom of the enclosure and placed vertically on the inner beam of the bracket for loading and unloading. This method requires attaching and removing the straps before and after lifting, and there is a risk of the battery pack tipping over and slipping during the lifting process. Furthermore, due to the weak structure and sealing requirements of the battery pack cover, a lifting structure cannot be designed on the cover itself. The lifting structure must be located on the side or bottom profile of the enclosure. However, since both the bracket and the battery pack are regular cuboids, the gap between the battery pack and the inner side of the bracket is small, resulting in limited lifting space. Considering both the reliability of the lifting structure and the pressure exerted by the chains and straps on the edges of the cover, the battery pack structure and lifting method are extremely limited.

[0003] To address the aforementioned issues, existing technologies provide a novel battery pack transfer and lifting tool. This tool uses slings and lifting components to transfer the battery pack. Connecting holes on the lifting components allow for the attachment and detachment of the tool from the battery pack via bolts or other connectors. During lifting, the tool maintains the stability of the battery pack and minimizes damage to the battery pack casing, thus improving safety to some extent. However, in practical applications, especially in scenarios involving long transport distances, there remains a risk that the battery pack may detach from the lifting device.

[0004] Therefore, there is an urgent need to design a battery pack transfer and hoisting tool to solve the problems existing in the current hoisting methods. Utility Model Content

[0005] The purpose of this utility model is to provide a battery pack transfer and hoisting tool, which aims to enhance its safety and reliability and further improve the protection of the battery pack during hoisting.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A battery pack transfer and hoisting tool includes: a lifting plate, a fixing plate, and a lifting connection assembly. The lifting plate surrounds the outer periphery of the battery pack. One end of the lifting plate is detachably connected to the battery pack's casing, and the other end of the lifting plate extends out of the battery pack's casing and is connected to the lifting connection assembly. The fixing plate is connected between adjacent lifting plates to restrict the movement of the lifting plate relative to the battery pack.

[0008] Preferably, along the length of the battery pack, at least two hanging plates are respectively provided at both ends of the battery pack, and the fixing plate is connected between adjacent hanging plates located at the same end.

[0009] Preferably, the fixing plate has a limiting groove recessed on the side facing the hanging plate, and the limiting groove is used to engage the hanging plate.

[0011] Preferably, the device also includes a first connector; the fixing plate has a first connecting hole, the hanging plate has a second connecting hole, the elastic buffer block has a third connecting hole, the first connector passes through the first connecting hole and the second connecting hole, and is connected to the third connecting hole.

[0012] Preferably, the portion of the hanging plate facing the box cover is bent outward to form a clearance portion, so that the clearance portion is spaced apart from the box cover.

[0013] Preferably, the lifting connection assembly includes a first sling, which is a sling, and the first sling corresponds one-to-one with the lifting plate and is used to connect to the lifting plate.

[0014] Preferably, the lifting connection assembly further includes a lifting frame, the lifting frame including support beams, the support beams being spaced apart and parallel along the width direction of the battery pack, the support beams being used to connect the first sling, and the distance between the support beams not greater than the width of the battery pack.

[0015] Preferably, the lifting connection assembly further includes an adjusting member, which is connected to the first sling in a one-to-one correspondence and is movably mounted on the supporting lifting beam;

[0016] And / or, the lifting connection assembly further includes a second sling and a first lifting ring, wherein a plurality of second slings are symmetrically distributed about the central axis of the lifting frame, one end of the second sling is connected to the lifting frame, and the other end of the second sling is connected to the first lifting ring.

[0017] Preferably, the adjusting component includes an adjusting block, a fixing block, and a second connecting member. The adjusting block has a U-shaped groove for connecting with the supporting beam. A first adjusting hole is provided through the inner wall of the U-shaped groove. The supporting beam has a plurality of second adjusting holes spaced apart along its length. The first adjusting hole can be selectively positioned opposite any one of the second adjusting holes. The second connecting member can be connected to the corresponding second adjusting hole through the first adjusting hole. The fixing block is connected to the adjusting block and is used to connect the first sling.

[0018] The beneficial effects of this utility model are as follows: The battery pack transfer and hoisting tool provided by this utility model can avoid the phenomenon of the lifting force directly acting on the box cover and squeezing the edge of the box cover during the hoisting process, thereby protecting the battery pack. In addition, by connecting the fixed plate between adjacent lifting plates, the lifting plates connected to the battery pack can form a stable overall structure, effectively restricting the lateral movement or rotation of the lifting plates relative to the battery pack, and preventing the connection structure between the lifting plates and the box shell from being subjected to lateral tensile or shear forces. This greatly reduces the risk of loosening of the connection between the lifting plates and the battery pack, further improving the safety and reliability of the hoisting process and the protection of the battery pack.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] The technical solution provided by this utility model will be described below with reference to the accompanying drawings and specific embodiments.

[0035] Combination Figures 1 to 4 As shown, this utility model provides a battery pack transfer and hoisting tool, which specifically includes a lifting plate 1, a fixing plate 2, and a lifting connection assembly 3. The lifting plate 1 surrounds the outer periphery of the battery pack 10. One end of the lifting plate 1 is detachably connected to the casing 101 of the battery pack 10, and the other end of the lifting plate 1 extends out of the casing cover 102 of the battery pack 10 and is connected to the lifting connection assembly 3. A fixing plate 2 connects adjacent lifting plates 1, and the fixing plate 2 is used to restrict the movement of the lifting plate 1 relative to the battery pack 10.

[0036] Specifically, refer to Figure 2 As shown, in this embodiment, one end of the lifting plate 1 is connected to the casing 101 of the battery pack 10, and the other end of the lifting plate 1 extends out of the cover 102 of the battery pack 10 and is connected to the lifting connection assembly 3. This places the connection point between the lifting plate 1 and the battery pack 10 on the casing 101 rather than on the cover 102, and the connection point between the lifting connection assembly 3 and the lifting plate 1 is away from the cover 102. This avoids the lifting force directly acting on the cover 102 and the phenomenon of squeezing the edge of the cover 102 during the lifting of the battery pack 10, thus protecting the battery pack 10. Furthermore, by connecting the fixing plate 2 between adjacent lifting plates 1, the lifting plates 1 connected to the battery pack 10 can form a stable overall structure, effectively limiting the lateral movement or rotation of the lifting plate 1 relative to the battery pack 10. This prevents the connection structure between the lifting plate 1 and the casing 101 from being subjected to lateral tensile or shear forces, greatly reducing the risk of loosening between the lifting plate 1 and the battery pack 10, thereby further improving the safety and reliability of the lifting process and the protection of the battery pack 10.

[0037] Furthermore, typically, the lifting plate 1 is a rigid sheet-like metal component, and this technical solution does not limit the material used for the lifting plate 1. Any material capable of exhibiting strong resistance to deformation under tension from any angle or direction during hoisting is acceptable, such as high-strength structural steel, aluminum alloy, stainless steel, etc. In addition, this technical solution does not limit the detachable connection method between the lifting plate 1 and the battery pack 10. The connection method can be freely selected from snap-fit ​​connections, threaded connections, plug-in connections, etc., as long as the connection is stable during hoisting and not prone to loosening, it is within the protection scope of this utility model.

[0038] Furthermore, in this embodiment, the portion of the lifting plate 1 facing the cover 102 is bent outward to form a clearance portion 11, so that the clearance portion 11 is spaced apart from the cover 102, preventing the lifting connection assembly 3 from squeezing the edge of the liquid cooling plate located on top of the battery pack 10 during the lifting process, thereby ensuring the safety of the liquid cooling plate.

[0039] In this embodiment, at least two hanging plates 1 are respectively provided at both ends of the battery pack 10 along its length, and a fixing plate 2 is connected between adjacent hanging plates 1 located at the same end. Specifically, refer to... Figure 1As shown, the length of the battery pack 10 is parallel to the X-axis. Two lifting plates 1 are respectively installed at both ends of the battery pack 10, and the two lifting plates 1 are fixedly connected by a fixing plate 2. This allows the lifting plates 1 at both ends to form a symmetrical structure relative to the center of gravity of the battery pack 10, thereby achieving circumferential force balance. Especially for the long, narrow battery pack 10, this effectively reduces the risk of the battery pack 10 tipping over during hoisting. Furthermore, by connecting the lifting plates 1 at the ends of the battery pack 10, compared to setting lifting points on the sides of the battery pack 10, interference between the lifting connection assembly 3 and the inner side of the bracket is effectively avoided, saving space and facilitating the placement of the battery pack 10 on the bracket.

[0040] Of course, it is understandable that in other parallel embodiments, the end of the battery pack 10 may also be provided with two or more lifting plates 1. By providing more lifting plates 1, the weight that the lifting device can bear can be further increased, making it suitable for heavy trucks, construction machinery and other scenarios that carry large-capacity heavy battery packs 10. Therefore, the number of lifting plates 1 can be reasonably adjusted according to the actual working conditions.

[0041] In this embodiment, reference Figure 3 As shown, a limiting groove 21 is recessed on the side of the fixed plate 2 facing the hanging plate 1. The limiting groove 21 is used to engage the hanging plate 1, which reduces the risk of swinging caused by relative rotation between the hanging plate 1 and the fixed plate 2 during hoisting, thereby improving the connection stability between the hanging plate 1 and the fixed plate 2. At the same time, the limiting groove 21 can further restrict the movement of the hanging plate 1, ensuring a good and reliable connection between the hanging plate 1 and the battery pack 10. Preferably, the shape of the limiting groove 21 is adapted to the shape of the hanging plate 1, further enhancing the limiting ability of the hanging plate 1.

[0042] In this embodiment, the tool also includes an elastic buffer block 4, which is sandwiched between the lifting plate 1 and the battery pack 10. Specifically, the elastic buffer block 4 is preferably made of a non-metallic material, such as rubber, silicone, or elastic plastic (EVA, TPR). The elastic buffer block 4 can effectively prevent the lifting plate 1 from directly contacting the battery pack 10 and crushing the surface treatment layer of the casing 101 during the lifting process. It can also effectively absorb the impact and vibration during the lifting process, preventing the battery pack 10 from being damaged by rigid collision.

[0043] It should be further noted that the battery pack 10 typically has a profile end plate 103 at its end. Furthermore, in embodiments of this technical solution, reference is made to... Figure 2 , Figure 3As shown, at least one end face of the profile end plate 103 is also provided with a corner protrusion 1031, and a threaded hole is provided at the corner protrusion 1031. A through hole 12 is provided on the hanging plate 1 at a position opposite to the threaded hole. A threaded component 20 (bolt or screw) is threadedly connected to the threaded hole through the through hole 12 to fix the hanging plate 1 to the profile end plate 103. Compared with opening lifting points at other positions of the profile end plate 103, this technical solution can save space to the maximum extent, avoid damage to the integrity of the profile, and avoid affecting the load-bearing capacity. In addition, the elastic buffer block 4 provided between the profile end plate 103 and the hanging plate 1 can fill the irregular gap between the hanging plate 1 and the profile end plate 103 through contour design, so as to enhance the compactness of the connection between the hanging plate 1, the profile end plate 103 and the elastic buffer block 4.

[0044] In this embodiment, the tool further includes a first connector 5; the fixing plate 2 has a first connecting hole 22, the hanging plate 1 has a second connecting hole 13, and the elastic buffer block 4 has a third connecting hole (not shown in the figure). The first connector 5 passes through the first connecting hole 22 and the second connecting hole 13, and is connected to the third connecting hole. Specifically, refer to... Figure 3 As shown, the first connecting piece 5 is a bolt, the first connecting hole 22 and the second connecting hole 13 are both sliding holes, and the third connecting hole is a threaded hole that can be concentrically set with the first connecting hole 22 and the second connecting hole 13. After the fixing plate 2, the hanging plate 1 and the elastic buffer block 4 are attached together in sequence, the first connecting piece 5 passes through the first connecting hole 22 and the second connecting hole 13 in sequence and is threadedly connected to the third connecting hole, thereby realizing the fixed connection of the hanging plate 1, the elastic buffer block 4 and the fixing block 342. This allows the elastic buffer block 4 to be stably clamped between the profile end plate 103 and the hanging plate 1, preventing relative sliding and slippage, making the overall structure more stable and safer. In addition, it facilitates the replacement and maintenance of the elastic buffer block 4, ensuring that it maintains good elastic buffering performance.

[0045] In this embodiment, the lifting connection assembly 3 includes a first sling 31, which is a sling. The first sling 31 corresponds one-to-one with the lifting plate 1 and is used for connection to the lifting plate 1. Specifically, refer to... Figure 1 As shown, the first sling 31 has four slings, which are connected to the four lifting plates 1 respectively. The first sling 31 is a sling. Since the sling is flatter than the chain, it can save more lifting space than the chain. It can reduce the risk of interference between the first sling 31 and the cover 102 if there is an angle between them during the lifting process. This can prevent the cover 102 from being scratched and further improve the protection of the battery pack 10 during the lifting process.

[0046] Optionally, in this embodiment, reference is made to... Figure 2As shown, the lifting connection assembly 3 also includes a shackle 32, which can connect the first sling 31 and the lifting plate 1, making the tool a split structure. This not only facilitates transportation and saves space, but also reduces maintenance costs. If a single first sling 31 fails, there is no need to replace the entire assembly. At the same time, different specifications of the first sling 31 or shackle 32 can be flexibly replaced according to lifting requirements, which greatly improves the versatility and adaptability of the tool.

[0047] In this embodiment, the lifting connection assembly 3 further includes a lifting frame 33, which includes support beams 331. The support beams 331 are spaced apart and parallel to each other along the width direction of the battery pack 10. The support beams 331 are used to connect the first sling 31, and the distance between the support beams 331 is not greater than the width of the battery pack 10. Specifically, refer to... Figure 1 As shown in the figure, the width direction of the battery pack 10 is indicated by the Y-axis. The lifting frame 33 is a rectangular structure. Two beams parallel to the width direction of the battery pack 10 in the lifting frame 33 are configured as two supporting lifting beams 331. Each supporting lifting beam 331 is connected to two first slings 31 located on the same side, so that the four first slings 31 can be symmetrically arranged with the central axis of the lifting frame 33 as the center, ensuring the balance and stability of the first slings 31 in lifting the battery pack 10. In addition, by setting the distance between the supporting lifting beams 331 to be no greater than the width of the battery pack 10, the first slings 31 connected to the supporting lifting beams 331 can be tilted inward, thereby effectively avoiding interference and friction between the outer side of the first sling 31 and the inner side of the bracket during lifting, ensuring that the battery pack 10 can be smoothly and safely lowered into the bracket.

[0048] Preferably, the lifting frame 33 also uses metal components with excellent deformation resistance. Furthermore, in this embodiment, the lifting frame 33 has cross-shaped reinforcing beams 332 inside, which further improve the deformation resistance and structural stability of the supporting lifting beam 331, and further reduce the safety risks during the lifting process.

[0049] In this embodiment, the lifting connection assembly 3 further includes an adjusting member 34, which is connected one-to-one with the first sling 31, and the adjusting member 34 is movably mounted on the supporting beam 331, so that the connection position of the first sling 31 on the supporting beam 331 can be adjusted as needed.

[0050] Specifically, refer to Figure 1 , Figure 4As shown, the adjusting member 34 includes an adjusting block 341, a fixing block 342, and a second connecting member 343. The adjusting block 341 has a U-shaped groove 3411, which is used to connect with the supporting beam 331 to prevent the adjusting member 34 from slipping off the supporting beam 331. The inner wall of the U-shaped groove 3411 is provided with a first adjusting hole 3412. The supporting beam 331 is provided with a plurality of second adjusting holes 3311 at intervals along its length. The first adjusting hole 3412 can be selectively arranged opposite to any one of the second adjusting holes 3311. At this time, the second connecting member 343 can be connected to the corresponding second adjusting hole 3311 through the first adjusting hole 3412. The fixing block 342 is connected to the adjusting block 341 and is used to connect the first sling 31. The adjusting component 34 has a simple structure and is easy to use. When it is necessary to adjust the connection position of the adjusting component 34 on the support beam 331, it is only necessary to remove the second connecting component 343 and move the adjusting block 341. The adjusting block 341 can drive the fixed block 342 and the first sling 31 connected to the fixed block 342 to move relative to the support beam 331. After moving into place, the adjusting block 341 is fixedly connected to the support beam 331 through the second connecting component 343, which can complete the change of the connection position of the first sling 31 on the support beam 331, thereby ensuring that the center of the battery pack 10 can coincide with the center of the tool and avoid tilting during lifting. In addition, by adjusting the distance between the two first slings 31 on opposite sides along the X-axis to be less than the length of the battery pack 10, it can be ensured that the lifting plate 1 can be close to the battery pack 10 during the lifting process, preventing the bolts or screws used to connect the lifting plate 1 and the profile end plate 103 from being broken by shear force, thereby ensuring safety during the lifting process.

[0051] Furthermore, in this embodiment, reference is made to... Figure 4 As shown, a second lifting ring 344 is fixedly provided at the bottom of the fixing block 342. The second lifting ring 344 can also be connected to the first lifting cable 31 through a shackle 32, so that the first lifting cable 31 can be completely removed from the tool for replacement and maintenance, making it more convenient and flexible to use.

[0052] In this embodiment, the lifting connection assembly 3 further includes a second sling 35 and a first lifting ring 36. Preferably, four second slings 35 are provided, using a chain, symmetrically distributed around the central axis of the lifting frame 33. One end of each second sling 35 is connected to the lifting frame 33, and the other end is connected to the first lifting ring 36. The first lifting ring 36 is used to connect with the lifting equipment, enabling the lifting equipment to smoothly lift and transport the battery pack 10 under the action of the second slings 35. Since the second slings 35 use a chain, which is typically made of metal, it has strong structural strength, thus capable of bearing the weight of the lifting device and the overall structure of the battery pack 10, providing good safety and stability.

[0053] Furthermore, in this embodiment, a third lifting ring 37 is also provided at the top of the lifting frame 33. The two ends of the second lifting cable 35 can be connected to the first lifting ring 36 and the third lifting ring 37 respectively through the shackle 32, so that the second lifting cable 35 can be removed separately and a more suitable specification can be selected for use by referring to the actual weight of the battery pack 10, which is more flexible and safer.
